[57] ABSTRACT O,N-di-a1iphatic hydrocarbon-S-[ N monoalkylcarbamylmethyl]-thionothiolphosphoric acid ester amides of general formula R NH (I) which possess insecticidal, acaricidal, and nematocidal properties.

8 Claims, No Drawings 0,N-DI-ALIPHATIC HYDROCARBONS-S-(N- MONOALKYLICARBANYL-METI-IYL)- THIONOTHIOLPHOSPHORIC ACID ESTER AMIDES The present invention relates to and has for its objects the provision of particular new O,N-di-aliphatic hydrocarbon-S-[N-monoalkylcarbamylmethyl]- thionothiolphas-phoric acid ester amides, i.e. O-alkylor alkenyl-N-monalkylor alkenyl-S-[N-(substitutedmonoalkyl)-carbamylmethyl]-thiomothiolphosphoric acid ester amides, which possess insecticidal, acaricidal and nematocidal properties, ctive active in the form of mixtures of such compounds with solid and liquid dispersible carrier vehicles, and methods for producing such compounds and for using such compounds in a new way especially for combating pests, e.g. insects, ac arids and nematodes, with other and further objects becoming apparent from a study of the within specification and accompanying examples. T

lt is known from German Published Specification No. 1,138,977, Belgian Patent Specification No. 597,523, published Dutch Patent Application No. 6,902,315, and published Japanese Patent Applications 647/64 and 72352/66, that 0,0 -dialkyl-S-[N- monoalkylcarbamylmethyl]-thionothiol-phosphoric acid esters, for example 0,0-diethyl-S-[N-mono-1- methyl- 1 -cyano-ethyl-carbamylmethyl]- or 0,0- dimethyl-S-[ N-mono-2-methoxyethylcarbamylmethyl]-thionothiolphosphoric acid ester (Compounds A and B, respectively), possess insecticidal and acaricidal activity.

The present invention provides, as new compounds, the -alkyl-N-monoalkyl-S-[N'-monoalkylcarbamylmethyl]-thiono-thiolphosphoric acid ester amides of the general formula:

HUN

SN IUNfi (II) in which R and R have the meanings stated above, and M denotes an alkali metalequivalent, an alkaline earth metal equivalent or an optionally alkylsubstituted ammonium equivalent,

is reacted with a haloacetic acid amide of the general formula:

0 Ha1CH -NHR (In) in which R has the meaning stated above, and

Hal denotes a halogen atom, preferably a chlorine or bromine atom.

Surprisingly, the new O-alkyl-N-monoalkyl-S-[N'- mono-alkylcarbomylmethyl]-thionothiolphosporic acid ester amides of the formula (I) show a noteworthy nematocidal activity and, in some cases, also a better insecticidal and acaricidal activity than the known 0,- O-dialkyl-S-[N-monoalkylcarbamyl-methyl]-thionothiolphosphoric acid esters which are the chemically most closely comparable active compounds of the same type of activity. The compounds according to the invention therefore represent a genuine enrichment of the art.

If, for example, the sodium salt of O-ethyl-N-monoisopropyl-thionothiolphosphoric acid ester amide and bromo-acetic acid mono- 1 -methyl- 1 -cyano-ethyl amide are used as starting materials, the reaction course can be represented by the following equation:

CgHsO S CH3 Preferably, R and R each is a straight-chain or branched alkyl radical with up to four carbon atoms, namely methyl, ethyl, nor isopropyl or n-, iso-, sec.- or tert.- butyl or a cycloalkylradical with five to six carbon atoms; R preferably denotes a straight-chain or branched alkyl radical with up to four carbon atoms substituted by chlorine, cyano, methoxy or methylmercapto. As example of the starting materials of the formula (ll) which can be used, there are mentioned the potassium, sodium or ammonium salts of O-methyl-N- methyl-, O-methyl-N-ethyl-, O-methyl-N-n-propyl, O-methyl-N-isopropyl-, O-methyl-N-(n-, iso-, sec.-, tert.-)-butyl-, O-ethyl-N-methyl-, O-ethyl- N-ethyl-, O-ethyl-N-N-propyl-, O-ethyl-N-iso-propyl-, O-ethyl- N-(n-, iso-, sec.-, tert.-)-butyl-, O-n-propyl-N-methyl-, 0-n-propyl-N-ethyl-, O-n-propyl-N-n-propyl-, O-n- 'propyl-N- iso-propyl-, O-n-propyl-N-(n-, iso-, sec.-, tert.-)-butyl-, O-iso-propyl-N-methyl-, O-osp-propyl-N- ethyl-, O-iso-propyl-N-n-propyl, O-iso-propyl-N-isopropyl-, O-iso-propyl-N-(n-, iso-,sec.-, tert.-)-butyl-, O-(n-, iso-, sec.-, tert.-)-butyl-N-ethyland .O-(n-, iso-, sec.-, tert.-)-butyl-N-iso-propyl-thiono-thiolphosphoric acid ester amides.

The preparative process is expediently carried out using a solvent or diluent, for which purposes all inert organic solvents and diluents are suitable, especially aliphatic and aromatic optionally chlorinated hydrocarbons, such as benzene, toluene, xylenes, benzine, methylene chloride, chloroform, carbon tetrachloride and chlorobenzene; ethers, such as diethyl and dibutyl ethers and dioxane; ketones, such as acetone and methylethyl, methylisopropyl and methylisobutyl ketones; nitriles, such as acetonitrile; and alcohols such as methanol, ethanol and isopropanol. In some cases also water is a suitable solvent or diluent. The reaction temperatures can be varied within a fairly wide rangeln general, the reaction is at about to 100C, preferably about 0 to 40C. The effected reaction is, in general, carried out at normal pressure.

When carrying out the preparative process, the compounds of the formula (II) and the haloacetic acid amides of formula (III) are, in most cases, used in substantially equimolar amounts. An excess of one or the other of the reactants brings no substantial advantages. The reaction is preferably effected in one of the abovementioned solvents at about 0 to 40C. The reaction solution is expediently stirred afterwards for several hours and thereafter worked-up by any customary method.

The compounds according to the invention are obtained in most cases in the form of colorless to slightly brown-colored, viscous, water-insoluble oils which cannot be distilled without decomposition but which can, by so-called slight distillation, that is longer heating to moderately elevated temperatures under reduced pressure, be freed from the last volatile components and in this way be purified. For their characterization, the refractive index is especially suitable. The compounds obtainable in crystalline form are characterized by their melting points.

As already mentioned, the new compounds according to the invention are distinguished by outstanding nematocidal, insecticidal and acaricidal properties. They possess a good effectiveness against both sucking and biting insects, Diptera, mites, as well as a systemic activity. The products may therefore be used with success in crop protection against the most diverse animal pests.

To the sucking insects contemplated herein there belong, in the main aphids (Aphidae') such as the green peach aphid (Myzus persicae), the bean aphid (Doralis fabae), the bird cherry aphid (Rhopalosiphum padi), the pea aphid (Macrosiphum pisi) and the potato aphid (Macrosiphum solamfolii), the currant gall aphid (Cryptomyzus korschelti), the rosy apple aphid (Sappaphis mali), the mealy plum aphid (Hyalopterus arundinis) and the cherry black-fly (Myzus cerasi); in addition, scales and mealybugs (Coccina), for example the oleander scale (Aspidiotus hederae) and the soft scale (Lecam'um hesperidum) as well as the grape mealybug (Pseudo-coccus maritimus); thrips (Thysanoplera), such as Hercinothrips femoralis, and bugs, for example the beet bug (Piesma quadrata), the red cotton bug (Dysdercus imermedius), the bed bug (Cimex lectularius), the assassin bug (Rhodm'us prolixus) and Chagas' bug (Trialoma infestans) and, further, cicadas, such as Euscelis bilobatus and Nephotettix bipunctatus; and the like.

When applied against pests harmful to health and pests of stored products, particularly flies and mosquitoes, the compounds are also distinguished by an outstanding residual activity on wood and clay, as well as a good stability to alkali on limed substrates The active compounds according to the instant invention can be utilized, if desired, in the form of the usual formulations or compositions with conventional inert (i.e. plant compatible or herbicidally inert) pesticide diluents or extenders, i.e. diluents, carriers or extenders of the type usable in conventional pesticide formulations or compositions, e.g. conventional pesticide dispersible carrier vehicles such as gases, solutions, emulsions, suspensions, emulsifiable concentrates, spray powders, pastes, soluble powders, dusting agents, granules, etc. These are prepared in known manner, for instance by extending the active compounds with conventional pesticide dispersible liquid diluent carriers and/or dispersible solid carriers optionally with the use of carrier vehicle assistants, e.g. conventional pesticide surface-active agents, including emulsifying agents and/or dispersing agents, whereby, for example, in the case where water is used as diluent, organic solvents may be added as auxiliary solvents. The following may be chiefly considered for use as conventional carrier vehicles for this purpose: aerosol propellants which are gaseous at normal temperatures and pressures, such as freon; inert dispersible liquid diluent carriers, including inert organic solvents, such as aromatic hydrocarbons (e.g. benzene, toluene, xylene, etc.), halogenated, especially chlorinated, aromatic hydrocarbons (e.g. chloro-benzenes, etc.), paraffins (e.g. petroleum fractions), chlorinated aliphatic hydrocarbons (e.g. methylene chloride, etc.), alcohols (e.g. methanol, ethanol, propanol, butanol, etc.), amines (e.g. ethanolamine, etc.), ethers, ether-alcohols (e.g. glycol monomethyl ether, etc. amides (e.g. dimethyl fomamide, etc.), sulfoxides (e.g. dimethyl sulfoxide, etc.), ketones (e.g. acetone, etc. and/or water; as well as inert dispersible finely divided solid carriers, such as ground natural minerals (e.g. kaoline, clays, alumina, silica, chalk, i.e. calcium carbonate, talc, attapulgite, montmorillonite, kieselguhr etc.) and ground synthetic minerals (e.g. highly dispersed silicic acid, silicates, e.g. alkali silicates, etc.); whereas the following may be chiefly considered for use as conventional carrier vehicle assistants, e.g. surface-active agents, for this purpose: emulsifying agents, such as non-ionic and/or anionic emulsifying agents (e.g. polyethylene oxide esters of fatty acids, polyethylene oxide ethers of fatty alcohols, alkyl-sulfonates, aryl sulfonates, etc., and especially alkyl arylpolyglycol ethers, magnesium stearate, sodium oleate, etc.); and- /or dispersing agents, such as lignin, sulfite waste liquors, methyl cellulose, etc. r i

Such active compounds may be employed alone or in the form of mixtures with one another and/or with such solid and/or liquid dispersible carrier vehicles and/or with other known compatible active agents, especially plant protection agents, such as other acaricides, insecticides and nematocides, fungicides, bactericides, or rodenticides, herbicides, fertilizers, growth-regulating agents, etc., if desired, or in the form of particular dos-i age preparations for specific application made therefrom, such as solutions, emulsions, suspensions, powders, pastes, and granules which are thus ready for use.

As concerns commercially marketed preparations, these generally contemplate carrier composition mixtures in which the active compound is present in an amount substantially between about 0.1-95 percent by weight, and preferably 0.5-90 percent by weight, of the mixture, whereas carrier composition mixtures suitable for direct application or field application generally contemplate those in which the active compound is present in an amount substantially between about 0.0001-10 percent, preferably 0.01-1 percent, by weight of the mixture. Thus, the present invention contemplates over-all compositions which comprise mixtures of a conventional dispersible carrier vehicle such as (l) a dispersible inert finely divided carrier solid, and/or (2) a dispersible carrier liquid such as an inert organic solvent and/or water preferably including a surface-active effective amount of a carriervehicle assistant, e.g. and surface-active agent, such as an emulsifying agent and- /or a dispersing agent, and an amount of the active compound which is effective for the purpose in question and which is generally between about 0.0001-95 percent, and preferably 0.01-95 percent, by weight of the mixture.

The active compounds can also be used in accordance with the well known ultra-low-volume process with good success, i.e. by applying such compound if normally a liquid, or by applying a liquid composition containing the same, via very effective atomizing equipment, in finely divided form, e.g. average particle diameter of from 50-100 microns, or even less, i.e. mist form, for example by airplane crop spraying techniques. Only up to at most about a few liters/hectare are needed, and often amounts only up to about 15 to 1000 g/hectare, preferably 40 to 600 g/hectare, are sufficient. In this process it ispossible to use highly concentrated liquid compositions with said liquid carrier vehicles containing from about 20 to about 95 percent by weight of the active compound or even the 100 percent active substance alone, e.g. about 20-100 percent by weight of the active compound.

Furthermore, the present invention contemplates methods of selectively killing, combating or controlling pests, e.g. insects, acarids and nematodes, which comprises applying to at least one of correspondingly (a) such insects, (b) such acarids, (e) such nematodes, and '(d) the corresponding habitat thereof, i.e. the locus to be protected, a correspondingly combative or toxic amount, i.e. an insecticidally, acaricidally or nematocidally effective amount of the particular active compound of the invention alone or together with a carrier vehicle as noted above. The instant formulations or compositions are applied in the usual manner, for instance by spraying, atomizing, vaporizing, scattering, dusting, watering, squirting, sprinkling, pouring, fumigating, and the like. v

[T will be realized, of course, that the concentration of the particular active compound utilized in admixture with the carrier vehicle will depend upon the intended EXAMPLE 1 -s-crn-d-NH-cm-cm-o on,

lCaHrNH (2) To 48.6 g (0.22 mole) of the sodium salt of O-ethyl- N-monoisopropyl-thionothiolphosphoric acid ester amide in 200 cc of acetonitrile there are added slowly at room temperature, 30.4 g (0.20 mole) of chloroacetic acid Z-methoxy-ethyl amide in 100 cc of acetonitrile. The reaction mixture is afterwards stirred overnight at room temperature; it is poured into water; the mixture is taken up in benzene; the organic phase is washed neutral with water; it is dried over sodium sulfate; filtration is effected and the filtrate is concentrated. 50.0 g (79.6 percent of theory) of O-ethyl-N- monoiso-propyl-S-[N'-2-methoxyethylcarbamylmethyl]-thionothiolphosphoric acid ester amide are obtained as a brown oil of refractive index n,,- of

Cabbage plants (Brassica oleracea) are watered with, in each case, 50 ml of the preparation of active compound so that the preparation of active compound penetrates into the soil without wetting the leaves of the cabbage plants. The active compound is taken up by the cabbage plants from the soil and so reaches-the leaves. There are applied 12.5 mg of active compound to 100 g of soil (weighed air-dry).

After the times stated, the plants are infested with peach aphids (Myzus persicae) and their mortality is, in each case, determined after three days. 100 percent means that all the aphids were killed; 0 percent means that none of the aphids were killed.

The active compounds, concentrations of active compound, evaluation times and results can be seen from the following Table 5:

The preparation of active compound is intimately mixed with soil which is heavily infested with the test nematodes. The concentration of the active compound in the preparation is of practically no importance; only the amountof active compound per unit volume of soil, which is given in p.p.m., is decisive. The soil is filled into pots, lettuce is sown in and the pots are kept at a greenhouse temperature of 27C. After four weeks, the lettuce roots are examined for infestation with nematodes, and the degree of destruction of the active compound is determined as a percentage. The degree of effectiveness is 100 percent when infestation is completely avoided; it is 0 percent when the infestation is exactly the same as in the case of the control plants in untreated soil which has been infested in the same manner.
